    摘要： PROBLEM TO BE SOLVED: To provide 4-keto-D-arabonic acid as a novel compound and its production method, and 4-keto-D-arabinose and its production method, which is the intermediate product of 4-keto-D-arabonic acid.SOLUTION: By cultivating 4-keto-D-arabonic acid-producing bacteria belonging to Gluconacetobacter or Gluconobacter, for example, cultivating Gluconacetobacter liquefaciens having ability of producing 4-keto-D-arabonic acid, in a cultivation medium containing D-glucose, D-gluconic acid or 2-keto-D-gluconic acid, 2,5-diketo-D-gluocnic acid (25DKA) is produced as a metabolite, which is further metabolized to produce 4-keto-D-arabonic acid. After isolating washed cells or a cytoplasmic membrane fraction of the Gluconacetobacter liquefaciens, when the washed cells or the cytoplasmic membrane fraction is made to react with 25DKA, not only 4-keto-D-arabonic acid but 4-keto-D-arabinose that is an intermediate product of 4-keto-D-arabonic acid can be produced.
